Non-family Shareholder Governance and Green Innovation of Family Firms: A Socio-emotional Wealth Theory Perspective
We draw on socio-emotional wealth (SEW) theory to investigate the influence of non-family shareholder governance (NFSG) on green innovation in family firms. We find that non-family shareholder holding has no significant impact on green innovation, but the directors appointed by non-family shareholders (NFSDAs) significantly promote the implementation of green innovation strategies in family firms. The underlying mechanisms are characterized by NFSG bringing valuable resources and promoting the firm reputation, which further facilitates green innovation. The effect of NFSG is more pronounced for entrepreneurial family firms and family firms located in high institutional efficiency areas. The green professional backgrounds of NFSDAs and having excess NFSDAs also effectively promote green innovation. Finally, green innovation promotes the long-term orientation of family firms. Through this study, we draw on SEW theory to enrich research on NFSG and green innovation in family firms. Our findings can help family firms achieve a solid basis for long-term orientation
Empirical approximation to invariant measures of non-degenerate McKean--Vlasov dynamics
This paper studies the approximation of invariant measures of McKean--Vlasov
dynamics with non-degenerate additive noise. While prior findings necessitated
a strong monotonicity condition on the McKean--Vlasov process, we expand these
results to encompass dissipative and weak interaction scenarios. Utilizing a
reflection coupling technique, we prove that the empirical measures of the
McKean--Vlasov process and its path-dependent counterpart can converge to the
invariant measure in the Wasserstein metric. The Curie--Weiss mean-field
lattice model serves as a numerical example to illustrate empirical
approximation.Comment: 21 pages, 1 figur
Identifying vital edges in Chinese air route network via memetic algorithm
Due to its rapid development in the past decade, air transportation system
has attracted considerable research attention from diverse communities. While
most of the previous studies focused on airline networks, here we
systematically explore the robustness of the Chinese air route network, and
identify the vital edges which form the backbone of Chinese air transportation
system. Specifically, we employ a memetic algorithm to minimize the network
robustness after removing certain edges hence the solution of this model is the
set of vital edges. Counterintuitively, our results show that the most vital
edges are not necessarily the edges of highest topological importance, for
which we provide an extensive explanation from the microscope of view. Our
findings also offer new insights to understanding and optimizing other
real-world network systems
